I have been having problems with PDR11 Ultimate crashing on startup for the past 3 weeks. I have tried dozens of different ways to fix it from reinstalling PDR11, to defragmenting my PC with no avail--until I uninstalled CATALYST CONTROL CENTER!
Some background: 3 weeks ago PDR11 was working fine until I had installed a virtual reality game on my system (now uninstalled due to trying to fix PDR11) which asked me to update my video driver/graphics card--so I did. I downloaded the CCC (Catalyst Control Center) from the AMD website, proceeded to update my video driver, then a few days later PDR11 began crashing.
So, if anyone is having similar problems with PDR11 please try uninstalling CATALYST CONTROL CENTER! Thanks for reading, hope this helps!
